SatLens

Turn your phone into a window to the cosmos. SatLens uses your camera, GPS, and motion sensors to overlay stars, planets, constellations, deep-sky objects, and satellites directly on the live sky — just point and discover. ✦ AUGMENTED REALITY SKY VIEW Open the app, hold your phone up, and see the night sky come alive. Every object is labeled and positioned in real time using precise astronomical calculations, so what you see on-screen matches exactly what's above you. ✦ STARS & DEEP-SKY OBJECTS Browse a rich catalog of bright stars and deep-sky treasures — nebulae, galaxies, and star clusters. Filter by magnitude to show only what's visible to the naked eye or dig deeper with binoculars and telescopes. ✦ PLANETS & SOLAR SYSTEM Instantly locate Mercury, Venus, Mars, Jupiter, Saturn, and more. Tap any planet to see its current distance, altitude, and azimuth. ✦ SATELLITE TRACKING Track thousands of satellites overhead using live orbital data (TLE). See the ISS, Starlink passes, and other spacecraft glide across your sky in real time. Refresh orbital data with one tap to stay up to date. ✦ CONSTELLATIONS See constellation stick figures drawn across the stars. Switch between all 88 IAU constellations or a curated set of the most recognizable ones. ✦ OBSERVATION MODES Choose how you explore: • Celestial — focus on stars, planets, and deep-sky objects • Man-Made — spotlight satellites only • Mixed — see everything at once • Constellations — highlight constellation patterns • Visible — show only what's above the horizon right now ✦ FINDER & SAVED OBJECTS Looking for something specific? Set any object as a finder target and follow the on-screen guide to locate it. Save your favorite objects for quick access later. ✦ NIGHT MODE A red-tinted display preserves your dark-adapted vision during nighttime observing sessions. ✦ NO ACCOUNT REQUIRED SatLens works offline for star and planet identification. An internet connection is only needed to refresh satellite orbital data. Whether you're a curious beginner, an amateur astronomer, or a satellite spotter, SatLens puts the universe in your hands.
